      Weekly Report #03 - Sculpting Silhouette

Hi Blenderheads, Sculptors and Developers,

This week I was able to make some good progress! Most of the foundation 
is finished and now I am working on the fun parts, new geometry, shape 
approximation and detection.

My focus was on creating clean topology. The brush will only be used if 
it doesn’t distort and break the existing topology.

A clean topology is a challenge if the sculptor is able to draw any 
shape he deserves.

Therefore I designed a system to calculate the “spine” of the sketch 
drawn by the sculptor. The result is a tree-like representation of the 
shape. Now it is possible to generate a shape from this. Every branch 
will be modeled by geometry topologically identical to a subdivided cube.

I made a small gif to show the current stage of the tool:

To try it yourself, the current version is in the branch:

My plans for the next week are, t-intersections, ends and bridging the 
branches.

Have a nice weekend,

Sebastian Witt
